Application filed February as, 1912. Serial no. 680,028..

' To all whom it may concern Be it kno'wn that I, JUAN MANUEL SAN- crmzFONTECHA, subject of the King of Spain, residing at Mexico city, Mexico,have invented a new and useful Improvementin -Electric Switches, ofwhich the following is a specification.

This invention relates to improvements 1n electric switches.

The object of the mvention is to provide' a switch a simple and reliablearrangement of parts whichwill prevent injury to -moters or otherelectrical appliances in monophase-or polyphase circuits.

in the details of construction and arrangement of parts which will behereinafter described and particularly pointed out in the claims.

In the accompanying draw1ngs:-F1gu're V I is a face view of my improvedswitch, the

parts being in position when the'motor is not in use. Fig. II is'a Viewlooking from the front to illustrate the connections;

The letter L indicates a marble,-slate or other suitable base on whichtheelements constituting the switch are mounted. A series of spacedapartcontacts indicated at B, B and B? are arranged in circular form onthe base: L, and inside and spaced from said contacts is a second setofspaced apart -hontacts D, D and D Forming a partof the circulararrangement of the second set of contacts D, D and D is a third set ofspaced contacts E, E and E Each set of contacts is composed ofpreferably three semi-circular metal strips as clearly shown in thedrawings. Between and spaced from the adjacent sets of contacts andforming a part of the circular arrangement are plates K, K and K AleverJ, is pivotally mounted on the base and at one end said lever is formedwith a handle, while at its opposite end it is provided with acounter-weight 1. Se-

cured to and turning with the lever J, is a he invention comprehendsimprovements: P

he conminal post, A; the contact B is connected by a wirewith theterminal post A, and the contact B is connected by a wire with't-heterminal post A Below the-contacts are three interchange Patented. nee.11,1ai3.

able fuse plugs H, H and H mounted on strips G, G and G Below the fuse,plugs are terminal plugs F, F and F A wire connects the contact Ewith-the plug 'H and the latterv is connected by a...

wirewith the' terminal post F. The contact E is similarly connectedthrough the plug H, and terminal post F, so also, is the contact E,connected to plug. H and terminal ost F The, contact D is connected by awire with. the plate G, and thence the current passes through plug. H Hto terminal F. The contact D, is similarly connected to plate G and soalso is the contact D conplates K, K and K and as the latter are 11, 11.

wired, obviously the current is cut oil. To

start a motor, the handle of the lever J, is

turned so as to bring the arm C over the contacts D--B, the arm C overthe contacts D and the arm C overthe contacts D and B. The currentwillthen pass from terminals A, AQ A to the contacts B,

B and B throng-lithe arms C, C, C to passes from te minals A, A." ,and Ato 0011- tacts B, B and B "through the arms C, C and E, E, and E to theplates G, G, G and the respective plugs to the terminals F, F and F andthence to the motor. When the lever J reaches the last mentionedposition, it is caught behind the stop 0 and is held thereby andcaiaioot be released until the button M, is pressed to withdraw thestop. During the interval of the movement of the lever from its initialposition until the arms 6, C and C en age the contacts, E, E, E thecurrent does not pass through the fuse plates G, G, G but upon the lever"reaching its final position, the current is directed through the fuseplates and theplugs, so that if during the operation of the,

motor something should go Wrong, the fuse will blow out and the currentwill be cut oil.

Then by pressing the button M, the stop of movement of the two arms onthe pivoted lever, 'terminals connected with the said contacts, twoseries of spaced apart contacts arranged within and spaced from thefirst mentioned contacts, the two series of contacts being in the pathof movement of the two arms on the pivoted lever, one series. of

, contacts being of greater length than the companion series ofcontacts, terminals connected directly with each of the longer contactsin one of the series, a fuse in each of the connections between the saidlonger con- I tacts and the latter terminals, a connection between eachfuse and the shortercontacts in one of, the aforesaid series ofcontacts, theends of the arms being of sufiicient width to engage thefirst mentioned contacts and overlap-the spaces between the two se-Copies of this patent may be obtained. for

ries of contacts when the lever is'turned, and means for holding thelever in operative position. 4

2. In a switch of thecharacter described, the combination of a base, alever pivoted to the base, a counter-balance on the lever to return sameto normal position, arms movable with the lever, a set of contacts, asec- 0nd set of contacts, a third set of contacts, a:

set of terminals connected direct with the second set of contacts,- aset of fuses connected to the third mentioned set of contacts and theterminals, whereby when the lever is turned the arms Willdirect thecurrent through the second mentioned contacts and the terminals and whenfurther moved, will direct the current through the first and thirdmentioned set of contacts and the fuses and to the terminals, and aspring pressed button which engages the lever to hold same in operativeposit-ion.

In testimony whereof, I afiix my signature in presence of two witnesses.7
